Abstract

Der Erfindung liegt die Aufgabe zugrunde, eine Schutzscheibe für Warnbalken anzugeben, bei welcher Beeinträchtigungen der Ablesbarkeit einer von der Schutzscheibe geschützten Anzeigeeinheit wie z.B. eines Lochmatrixdisplays, durch Kondenswasserbildung weitestgehend vermieden sind.The invention has for its object to provide a protective window for warning bars, in which impairments of the readability of a protected from the protective screen display unit such. a perforated matrix display, are largely avoided by condensation.

Es wird eine Schutzscheibe (10) vorgeschlagen, die einen Abschnitt (12) erster Art zur Abdeckung einer Anzeigeeinheit umfaßt und bei der außerhalb des Hauptsichtfeldes auf die von der Schutzscheibe zu schützende Anzeigeeinheit wenigstens eine Sollkondenszone vorgesehen ist, wobei jede Sollkondenszone von einem Abschnitt (14, 16) zweiter Art gebildet wird, der eine Materialdicke aufweist, die geringer ist als die Materialdicke im Bereich des Abschnittes erster Art.

Figure imgaf001
A protective screen (10) is proposed, which comprises a section (12) of the first type for covering a display unit and in which outside the main field of view at least one nominal zone of condensation is provided on the display unit to be protected by the protective screen, each nominal zone of condensation being separated from a section (14 , 16) of the second type, which has a material thickness which is less than the material thickness in the region of the section of the first type.
